Overview
The Falk 046656 Steelflex grid coupling hub is a high-performance steel shaft hub engineered for reliable power transmission in industrial machinery. Part of the proven 1060T coupling family, this hub features precision-machined construction with alloy steel rated for demanding applications. The serpentine grid design connects two shafts while accommodating misalignment and damping shock loads.
Key Features
- Shot-peened alloy steel construction — hardened to spring strength for extended fatigue resistance and torque capacity
- Replace-in-place design — grid element changes without moving hubs or re-aligning shafts, reducing maintenance labor
- Misalignment accommodation — grid rocks, pivots, and floats within hub teeth to handle angular, parallel, and axial misalignment
- Shock absorption capability — torsional flexibility reduces peak loads and damps vibration during operation
- Long-term lubrication warranty — 5-year warranty when using Falk LTG (Long Term Grease) at installation
- Durable nitrile seals — prevent lubricant leaks and exclude water, dust, and contaminants
